Requested revision
Standard:IEEE 802.1AS-2020Clause:16.5.3.2.2
Clause title:CSN TLV
Rationale for revision
The specification for the CSN TLV seems incorrect and should be improved.

1)
Table 16-1—CSN TLV:
…
rxTime                                  offset 10, octets 12
neighborRateRatio         offset 14, octets 4
meanLinkDelay               offset 26, octets 12

The offset 14 of neighborRateRatio seems incorrect and should be 22.

2)
16.5.3.2.2.3 lengthField (UInteger16) says
“The value of the length is 46”

For 2020 “domainNumber” was added and IMHO this should have been increased to 47.
Proposed text
Change Table 16-1—CSN TLV:
neighborRateRatio         offset 22, octets 4

Change 16.5.3.2.2.3 lengthField (UInteger16)
The value of the length is 47
Impact on existing networks
This is merely an errata and should not have any impact on networks.
